I am trying to buy the Camera Pack app for Photoshop in the app on my iPhone 4 using the current update and I get the message that I need to buy the app first! Hello! I am IN the app! How can I fix this? Help please! Also, when I try to sign in to this support site my keyboard keeps dissapearing! this may or may not ever make it to posting. :-/

Sounds like you're seeing a paid features info screen. All it means to say is that you have to initiate the purchase from within our app. There are several ways to get the purchase process started: tap the 'New' button on the home screen, attempt to use one of the paid features (try one of the Express Camera advanced features, or try using Reduce Noise in the Editor).

Are you guys able to purchase In-app purchases from other applications or is this a Photoshop Express specific issue?

Could you please try out the following, this may help resolve the issue:
- Go to Settings>Store>Sign Out
- Exit settings
- Go back to settings and sign in again
- Now try to purchase again from Photoshop Express

If the above doesn't work, try the following:
- Go to Settings>Store>Sign Out
- Exit settings
- Go to Photoshop Express, initiate the purchase, it should ask for App Store credentials, enter the credential and see if it works

I think I have figured out the problem. The same iTunes account must be used for both download of the app and also the in-app purchase. When I let one iTunes account download the app, but try to use an alternate iTunes account to make the purchase, I can reproduce the error described ("I get the message that I need to buy the app first! Hello! I am IN the app!")

The iTunes account that tries to make the in app purchase must be the same iTunes account that initially downloaded the app in the first place. It's Apple's rule, and way of making sure users don't hand out apps to their friends, I suspect. Logging out and back in, or restarting the app won't help. I suggest uninstalling and reinstalling using the same iTunes account. And if you had already purchased the in-app features using this new or correct iTunes ID, and you don't see the Photoshop Express features you purchased, try using the Restore Purchase button in the app Settings.

Please let us know if this does or doesn't help, or match your problem.
